PEI-7

Description

PEI-7, or Polyethyleneimine-7, is a synthetic polymer widely used in haircare formulations for its versatile conditioning properties. This cationic ingredient is particularly effective in leave-in and rinse-off products, offering significant benefits for damaged or chemically treated hair.

PEI-7 functions as a film-forming agent, creating a protective layer on the hair shaft that helps to seal the cuticle and reduce moisture loss. This protective action contributes to improved hair manageability, reduced frizz, and enhanced shine. The polymer's positive charge allows it to adhere effectively to negatively charged hair surfaces, providing long-lasting conditioning effects.

In addition to its conditioning properties, PEI-7 aids in detangling and smoothing hair strands, making it easier to comb through wet or dry hair. It can also help to reduce static electricity, a common issue in dry or damaged hair. The ingredient is compatible with a wide range of other haircare components, making it a valuable addition to various product types, including shampoos, conditioners, and styling products.
